Malodor suppression by fragrance composition

Abstract

A method and composition for suppressing residential malodor, said composition comprising a fragrance having at least one perfume material which satisfies one of the following criteria, (1) contains a phenyl ring moiety and has an air diffusion coefficient of >5.7, or (2) contains a C-5 ring moiety, which also contains at least 1 carbon which is sp2 hybridized, and has an air diffusion coefficient of >4.4.

What is claimed is:  
     
         1 . A method for masking a residential malodor, said method comprising applying to the malodor source a composition containing a fragrance having at least one perfume material which satisfies one of the following criteria: 
 (1) contains a phenyl ring moiety and has an air diffusion coefficient of >5.7,    (2) contains a C-5 ring moiety, which also contains at least 1 carbon which is sp2 hybridized, and has an air diffusion coefficient of >4.4.    
     
     
         2 . A method as in  claim 1 , wherein said composition contains at least 25% of the perfume material satisfying criteria (1) or (2).  
     
     
         3 . A method as in  claim 1 , wherein the residential malodor is selected from the group consisting of trashcan odor, pet litter odor, urine odor and kitchen odor.  
     
     
         4 . A composition for suppressing residential malodor, said composition comprising: 
 a fragrance having at least one perfume material which satisfies one of the following criteria: 
 (1) contains a phenyl ring moiety and has an air diffusion coefficient of >5.7,  
 (2) contains a C-5 ring moiety, which also contains at least 1 carbon which is sp2 hybridized, and has an air diffusion coefficient of >4.4.  
   
     
     
         5 . A composition according to  claim 4 , wherein said fragrance contains at least 25% of the perfume material satisfying criteria (1) or (2).  
     
     
         6 . A composition according to  claim 4 , wherein said composition is selected from the group consisting of household cleaners, surfaces cleaners, skin cleaners, deodorant, air fresheners, and deodorizers.  
     
     
         7 . A method of controlling malodors on skin comprising: 
 applying to the skin a composition comprising: 
 a fragrance having at least one perfume material which satisfies one of the following criteria: 
 (1) contains a phenyl ring moiety and has an air diffusion coefficient of >5.7,  
 (2) contains a C-5 ring moiety, which also contains at least 1 carbon which is sp2 hybridized, and has an air diffusion coefficient of >4.4.  
 
   
     
     
         8 . A method of controlling malodors on skin according to  claim 7 , wherein said fragrance contains at least 25% of the perfume material satisfying criteria (1) or (2).  
     
     
         9 . A method for suppressing malodor in a solid surface, the method comprising the step of applying onto said solid surface, a composition comprising a fragrance having at least one perfume material which satisfies one of the following criteria: 
 (1) contains a phenyl ring moiety and has an air diffusion coefficient of >5.7, or    (2) contains a C-5 ring moiety, which also contains at least 1 carbon which is sp2 hybridized, and has an air diffusion coefficient of >4.4.    
     
     
         10 . A method as in  claim 9 , wherein the solid surface is selected from the group consisting of trashcan, diaper, and kitchen counter.  
     
     
         11 . A method for suppressing malodor in a pet litter, the method comprising the steps of: 
 contacting the pet litter with a composition containing a fragrance having at least one perfume material which satisfies one of the following criteria: 
 (1) contains a phenyl ring moiety and has an air diffusion coefficient of >5.7,  
 (2) contains a C-5 ring moiety, which also contains at least 1 carbon which is sp2 hybridized, and has an air diffusion coefficient of >4.4.  
   
     
     
         12 . A method as in  claim 3 , wherein the residential malodor is kitchen odor.  
     
     
         13 . A method as in  claim 12 , wherein the kitchen odor is selected from the group consisting of garlic, onion, and fish.
